Undocumented immigrants rescued from trailer at Sarita checkpoint

A tractor-trailer pulling tandem trailers was stopped at the checkpoint on U.S. Highway 77 north Thursday night, according to a news release. A dog alerted to the front trailer, prompting a second inspection. During that check, agents rescued the 21 immigrants who had no means of escape. The undocumented immigrants were provided medical evaluations and the driver was arrested.

Officials said they also made rescues in Alamo and Kingsville, with more than 40 undocumented immigrants found in cargo areas of vehicles.
